date skipping

[saltzmanjoelh]

Why does the date skip when I try to update it by 1, continuously?


var currentDate:Date = new Date();
var date:int = (currentDate.date + 1);
currentDate.date = date;



var currentDate:Date = new Date();
var date:int = (currentDate.date + 1);
currentDate.setDate = date;


If I continue to do this in Feb from 16th for 10 times I get
16, 17, 18, 20, 21, 22, 24, 25, 26, 28

It is recommended in the Adobe docs to do arithmetics with dates by converting the values into milliseconds so use this snipt

var currentDate:Date = new Date();
const millisecondsPerDay:int = 1000 * 60 * 60 * 24;
currentDate.setTime(currentDate.getTime() + millisecondsPerDay);

That still doesnt work for me



var millisecondsPerDay:int = 1000 * 60 * 60 * 24;
_currentDate.setTime(_currentDate.getTime() + millisecondsPerDay);


Here is what 30 days looks like starting on feb 2, 2009:

2
3
4
6
7
8
10
11
12
14
15
16
18
19
20
22
23
24
26
27
28
2
3
4
6
7
8
10
11
12

This works

_currentDate.setHours(24, 0, 0, 0);

var currentDate:Date = new Date();
const millisecondsPerDay:Number = 1000 * 60 * 60 * 24;
for(var i:int; i < 30; i++)
{
currentDate.setTime(currentDate.getTime() + millisecondsPerDay);
trace(currentDate.date);
}
int isn't capable of holding numeric representation of the date as it's max value is only 0x7fffffff, which is apparently not enough to represent date in milliseconds.

good catch! thanks for that.
